The connection between the flexible shell 100 and the mounting member 500 is stable, reliable, and practical.

[0092] In order to further improve the stability of the connection of the flexible shell 100, please refer to FIG. 4 In an embodiment, the crease 110 on the flexible shell 100 extends from the second end 102 to the front side of the first end 101, that is, the first end 101 is not provided with the crease 110, so that when the flexible shell 100 is in an inflated state, the first end 101 has a smaller expansion and deformation range, so that the embedding ring 520 is not easy to fall out of the embedding groove, and the stability of the connection between the mounting member 500 and the flexible shell 100 is further improved.

[0093] It can be understood that the embedding ring 520 and the extension cylinder 510 can be integrally provided or separately provided. Please refer to FIG. 10In an embodiment, the embedded ring 520 is integrally arranged with the extending cylinder 510, thereby improving the stability of the mounting member 500 in connection. The width of the embedded ring 520 on the extending cylinder 510 can be the same or different, which can be arranged according to the actual situation of the flexible shell 100.

[0094] Please refer to FIG. 4 and FIG. 10 In an embodiment, the embedded ring 520 extends along the thickness direction of the flexible shell 100, so that the embedded ring 520 is directly and deeply embedded in the flexible shell 100, and the mounting member 500 is more difficult to be pulled out of the port 100b, thereby improving the stability of the mounting member 500 in connection with the flexible shell 100. The mounting member 500 can be a hard member, and the mounting seat 400 is also a hard member, so that the two hard members are rigidly connected, thereby improving the reliability of the connection.

[0095] During the treatment process, the treatment head 10 needs to be held by hand, otherwise the treatment head 10 is easy to be pulled out of the cavity, affecting the treatment effect. In order to solve this problem, please refer to FIG. 3-4 In an embodiment, a anti-pulling-off part 120 is arranged between the first end 101 and the second end 102, the anti-pulling-off part 120 is close to the first end 101, and the outer diameter of the anti-pulling-off part 120 is smaller than the outer diameter of the second end 102. In use, the anti-pulling-off part 120 is clamped on the anti-pulling-off part 120 through the cavity, thereby playing a role of preventing the anti-pulling-off part 120 from being pulled out.

[0096] Please refer to FIG. 4 The anti-pulling-off part 120 can be formed by being inclined inward along the axis of the flexible shell 100 from the second end 102 to the first end 101; or the flexible shell 100 is provided with a tapered part tapering from the second end 102 to the first end 101; or a circle of anti-pulling-off grooves is arranged between the first end 101 and the second end 102.

[0097] In order to have a certain guidance to the inflation of the flexible shell 100, so as to prevent the inflation state of the flexible shell 100 from being irregular, please refer to FIG. 3-4 In an embodiment, the thickness of the electrode sheet 200 part of the flexible shell 100 is greater than the thickness of the creased part 110, that is, the thickness of the creased part 110 is relatively smaller than the thickness of the flexible shell 100 provided with the electrode sheet 200, so that the creased part 110 is easy to be inflated and supported.

[0098] Please refer to FIG. 4In an embodiment, the anti-extraction portion 120 comprises an extension portion 121 and a clamping portion 122, the extension portion 121 is close to the electrode sheet 200 relative to the clamping portion 122, the thickness of the anti-extraction portion 120 decreases from the extension portion 121 to the clamping portion 122, so that the flexible shell 100 can expand uniformly when inflated, so that the treatment area of the treatment head 10 (the area where the electrode sheet 200 is located) forms a column with uniform outer diameter, so as to fit the surface of the cavity. If the anti-extraction portion 120 is too thick, it will hinder the expansion of the flexible shell 100 close to the anti-extraction portion (the first end 101), forming an inverted conical column. Please refer to FIG. 4 In an embodiment, the thickness of the first end 101 of the flexible shell 100 increases from the clamping portion 122 to the first end 101, so that the first end 101 maintains its original shape when inflated and does not deform, so that the mounting member 500 does not fall out of the port 100b.

[0099] In order to facilitate the deformation of the flexible shell 100, in an embodiment, the thickness of the clamping portion 122 can be the same as the thickness of the crease portion 110. Please refer to FIG. 4 In an embodiment, the thickness of the flexible shell 100 provided with the electrode sheet 200 is uniform, so as to further uniformly inflate and expand the flexible shell 100.

[0100] Further, in order to avoid the mounting member 500 from falling off the flexible shell 100, please refer to FIG. 10-11 In an embodiment, the ring surface of the embedding ring 520 is provided with a strip-shaped protrusion 521 extending in the circumferential direction of the extension cylinder 510.

[0101] Please refer to FIG. 22-23 The strip-shaped protrusion 521 is arranged on the side of the embedding ring 520 facing the opening of the port 100b. By arranging the strip-shaped protrusion 521 on the ring surface of the embedding ring 520, the flexible shell 100 is deformed by extrusion, so that the strip-shaped protrusion 521 is embedded into the groove wall of the embedding groove. When the mounting member 500 is subjected to an outward pulling force, the strip-shaped protrusion 521 abuts against the flexible shell 100, increasing the friction between the mounting member 500 and the flexible shell 100, so that the embedding ring 520 is not easily separated, improving the stability of the connection between the mounting member 500 and the flexible shell 100.

[0102] Please refer to FIG. 10-11 The strip-shaped protrusion 521 can have multiple strip-shaped protrusions 521, and the multiple strip-shaped protrusions 521 are arranged at intervals in the circumferential direction of the extension cylinder 510, and / or the multiple strip-shaped protrusions 521 are arranged radially on the embedding ring 520, so as to further improve the stability of the connection between the mounting member 500 and the flexible shell 100. Unlike the above embodiment, please refer to FIG. 26-28 In an embodiment, the ring surface of the embedding ring 520 is not provided with the strip-shaped protrusion 521.

[0103] Please refer toFIG. 15-16 、 FIG. 23 The side of the mounting base 400 facing the flexible housing 100 can be provided with an annular protrusion 401, which is deformed by the flexible housing 100 when the mounting base 400 is mounted on the flexible housing 100, so that the annular protrusion 401 is embedded in the flexible housing 100. Moreover, the mounting base 400 is clamped with the mounting member 500, and the annular protrusion 401 abuts against the flexible housing 100, so that the flexible housing 100 is clamped between the mounting member 500 and the mounting base 400, and the annular protrusion 401 has the effect of strengthening the clamping and sealing.

[0104] Since the embedded ring 520 protrudes from the wall of the extension cylinder 510, in order to improve the strength of the embedded ring 520, please refer to FIG. 10 In an embodiment, the mounting member 500 is provided with a reinforcing rib 530, which is located on the outer wall surface of the extension cylinder 510 and connected to the embedded ring 520.

[0105] The reinforcing rib 530 is arranged on the side of the embedded ring 520 facing away from the port 100b, and connects the extension cylinder 510 and the embedded ring 520, so as to avoid the embedded ring 520 from being easily broken after being impacted, thereby improving the strength of the embedded ring 520 and the service life of the mounting member 500. Please continue to refer to FIG. 10 The number of reinforcing ribs 530 can be multiple, and the multiple reinforcing ribs 530 are arranged at intervals in the circumferential direction of the extension cylinder 510, so as to improve the strength of the embedded ring 520 as a whole.

[0106] Please refer to FIG. 10 In an embodiment, the multiple reinforcing ribs 530 are arranged at non-equidistant intervals in the circumferential direction of the extension cylinder 510. Please refer to FIG. 3 The inner wall surface of the first end 101 of the flexible housing 100 is provided with a positioning block 130, and a positioning groove is formed between the two reinforcing ribs 530. Since the multiple reinforcing ribs 530 are not arranged at equidistant intervals in the extension cylinder 510, the positioning block 130 cooperates with the positioning groove to prevent the mounting member 500 from being installed in the wrong position, so as to limit the installation position of the support assembly 600 in the flexible housing 100.

[0107] Please refer to FIG. 26 In an embodiment, the inner wall surface of the extension cylinder 510 is provided with a guide rib 540 extending in the length direction of the extension cylinder 510. On the one hand, the guide rib 540 guides the support assembly 600 inserted into the anti-impact port 510a, and the support assembly 600 slides along the guide rib 540. On the other hand, the guide rib 540 reduces the shaking of the support assembly 600 on the mounting member 500, and strengthens the structural strength of the mounting member 500.

[0108] Please refer to FIG. 3 and FIG. 12In an embodiment, the support assembly 600 of the treatment head 10 is used to support the flexible shell 100, so that the flexible shell 100 can maintain a certain shape and be smoothly inserted into the cavity. Please refer to FIG. 12-13 、 FIG. 29 The support assembly 600 is in the shape of a long strip to better support the flexible shell 100. Please refer to FIG. 4 and FIG. 10 The extension cylinder 510 is provided with a fool-proof opening 510a in communication with the inflation cavity 100a, and the fool-proof opening 510a is used for the support assembly 600 to pass through. By providing the fool-proof opening 510a on the extension cylinder 510, the support assembly 600 enters the inflation cavity 100a from the fool-proof opening 510a in a certain orientation, avoiding the support assembly 600 being installed in reverse, causing workers to rework or affecting product quality.

[0109] That is, the reinforcing ribs 530 on the extension cylinder 510 and the positioning blocks 130 on the inner wall of the flexible shell 100 play a fool-proof role in the installation of the mounting member 500. Then, the mounting member 500 is provided with the fool-proof opening 510a, which limits the insertion position of the support assembly 600, so that the support assembly 600 is installed in the flexible shell 100 at a certain angle.

[0110] Further, please refer to FIG. 10-11 In an embodiment, the fool-proof opening 510a is a cross slot, and the fool-proof opening 510a includes a first slot opening 510b and a second slot opening 510c intersecting with each other, and the width of the first slot opening 510b is greater than the width of the second slot opening 510c.

[0111] Please refer to FIG. 11 The outer diameter of the support assembly 600 is less than the width of the first slot opening 510b and greater than the width of the second slot opening 510c, so that when the treatment head 10 is assembled, the support assembly 600 can enter the inflation cavity 100a from the first slot opening 510b, realizing the positioning of the support assembly 600. When the support assembly 600 enters the second slot opening 510c, because the outer diameter of the support assembly 600 is greater than the width of the second slot opening 510c, the support assembly 600 cannot pass through the second slot opening 510c, and the worker can find that it is installed in reverse, so as to timely adjust the orientation of the support assembly 600, avoid rework afterwards, and improve the work efficiency of product assembly.

[0112] The connection mode of the mounting member 500 and the mounting seat 400 can be detachable connection or non-detachable connection. Please refer to FIG. 4 and FIG. 12 The mounting member 500 and the mounting seat 400 are detachably connected, so as to simplify the production process and facilitate the assembly operation of workers.

[0113] In an embodiment, the mounting member 500 and the mounting seat 400 are clamped. Specifically, please refer toFIG. 10-11 In one embodiment, the extension cylinder 510 is provided with a hooking member 511 near one end of the embedding ring 520, which is used to be clamped with the mounting base 400. The extension cylinder 510 is outwardly protruded at one end located at the port 100b to form a hooking part 511a, which is clamped with the mounting base 400 through the hooking member 511 to realize the connection of the mounting member 500 and the mounting base 400. In addition, please refer to FIG. 22-23 When the mounting member 500 is clamped with the mounting base 400, the embedding ring 520 clamps the end of the first end 101 of the flexible shell 100 with the mounting base 400, thereby playing a sealing effect to avoid liquid entering the inside of the flexible shell 100 from the gap between the end of the first end 101 and the mounting base 400.

[0114] Please refer to FIG. 12-13 The mounting base 400 is provided with a buckling member 403 matched with the hooking member 511.

The flexible shell 100 is mounted on the mounting member 500 through the clamping of the hooking member 511 of the mounting member 500 and the buckling member 403 of the groove wall of the receiving groove 400b.

[0117] Please refer to FIG. 15 The mounting base 400 is provided with an inflation hole 400a communicated with the inflation cavity 100a, so that after the mounting base 400 is connected with the handle 20, the inflation pump in the handle 20 inflates the flexible shell 100 through the inflation hole 400a to treat the user.

[0118] Since the treatment head 10 needs to be cleaned after the treatment course, the treatment head 10 is detached from the handle 20 during the cleaning. In order to prevent liquid from entering the inflation cavity 100a from the inflation hole 400a of the mounting base 400 during the cleaning process, in one embodiment, please refer to FIG. 13 and FIG. 22The treatment head 10 further comprises a sealing gasket 730 mounted on the inner side of the mounting base 400; the treatment head 10 further comprises a sealing member 710 elastically abutting against the sealing gasket 730 to block the inflation hole 400a.

[0119] With reference to FIG. 22 、 FIG. 36-37 The sealing gasket 730 is located on the side of the mounting base 400 away from the handle 20 and tightly abuts against the inner wall surface of the mounting base 400 to prevent liquid from entering from the mounting base 400 and the sealing gasket 730. The sealing member 710 elastically abuts against the sealing gasket 730, and the outer diameter of the sealing member 710 is greater than the hole diameter of the inflation hole 400a. Before the treatment head 10 is mounted on the handle 20, the sealing member 710 blocks the inflation hole 400a under the action of the elastic force to isolate the inflation cavity 100a from the external environment, thereby preventing liquid from entering the inflation cavity 100a during the cleaning process of the treatment head 10 and avoiding internal circuit structure short circuit, and preventing the treatment head 10 from leaking air when the treatment head 10 is inflated, thereby improving the air tightness of the treatment head 10.

[0162] Further, please refer to FIG. 1-2In an embodiment, one of the mounting base 400 and the handle 20 is provided with the clamping block 402, and the other is provided with the clamping groove 20b. The clamping block 402 is clamped in the clamping groove 20b, so as to connect the mounting base 400 and the handle 20.

[0163] Please continue to refer to FIG. 1-2 In an embodiment, the outer wall of the mounting base 400 is provided with the clamping block 402, and the handle 20 is provided with the clamping groove 20b. The handle 20 is provided with the mounting groove 20a for accommodating the mounting base 400. The groove wall of the mounting groove 20a is provided with the clamping groove 20b. The flexible outer shell 100 is connected to the handle 20 by the cooperation of the clamping block 402 and the clamping groove 20b.

[0164] In order to facilitate the operation of the user, please refer to FIG. 1 In an embodiment, the clamping groove 20b includes the passage groove 20c for the clamping block 402 to extend into and the clamping groove 20d extending along the circumference of the handle 20. The passage groove 20c and the clamping groove 20d are in communication.

[0165] Please refer to FIG. 1-2 The clamping block 402 enters the clamping groove 20b through the passage groove 20c. The mounting base 400 is rotated, so that the clamping block 402 moves in the clamping groove 20d. The clamping groove 20d clamps the clamping block 402, so as to prevent the clamping block from being separated from the clamping groove 20d. Since the flexible outer shell 100 is mounted on the mounting base 400, the connection between the flexible outer shell 100 and the handle 20 is achieved. The flexible outer shell 100 is detached in the opposite way. First, the flexible outer shell 100 is rotated. The clamping block 402 of the mounting base 400 moves in the clamping groove 20d. The clamping block 402 exits the clamping groove 20b through the passage groove 20c, so as to quickly separate the flexible outer shell 100 from the handle 20. Please refer to FIG. 1 Through the clamping groove 20b structure, the installation and dismounting of the flexible outer shell 100 and the handle 20 are facilitated, and the stability of the connection between the flexible outer shell 100 and the handle 20 is improved.

[0166] Please refer to FIG. 21-22 The handle 20 is provided with the abutting column 21 corresponding to the inflation hole 400a. When the handle 20 is connected to the mounting base 400, the abutting column 21 extends into the inflation hole 400a and abuts against the sealing element 710, so as to separate the sealing element 710 from the inflation hole 400a and open the inflation hole 400a. Please continue to refer to FIG. 21-22In an embodiment, the abutting column 21 of the handle 20 can be provided with a gas inlet 21a, which can be formed on the end face of the abutting column 21. The abutting column 21 is connected with the air pump through the air charging pipe 22, which is in communication with the gas inlet 21a. Thus, the gas can enter the accommodating groove 600a from the air charging pipe 22 through the gas inlet 21a, and then enter the air charging cavity 100a of the flexible outer shell 100 from the accommodating groove 600a.

[0167] Please refer to FIG. 31-32 In an embodiment, the handle 20 is provided with a limiting column 23a, which can be extended into and withdrawn from the treatment head 10. The mounting seat 400 is provided with a limiting hole 400d, which accommodates the limiting column 23a and is deviated from the axis of the treatment head 10. When it is needed to detach the treatment head 10, the limiting column 23a is first moved to the inside of the handle 20, and then the limiting column 23a is withdrawn from the limiting hole 400d. Then, the treatment head 10 is rotated, the clamping block 402 on the mounting seat 400 is moved in the clamping groove 20b, and finally the clamping block 402 is separated from the clamping groove 20b, so as to separate the handle 20 from the treatment head 10. When it is needed to connect the handle 20 with the treatment head 10, the treatment head 10 is rotated, and the limiting column 23a is extended into the limiting hole 400d, which indicates that the handle 20 and the treatment head 10 have been matched.

[0168] When the handle 20 and the treatment head 10 are matched, the limiting column 23a is extended into the limiting hole 400d, and the limiting hole 400d is deviated from the axis of the treatment head 10 on the mounting seat 400. The limiting column 23a hinders the rotation of the treatment head 10, so that the treatment head 10 cannot be rotated. It should be noted that when the limiting column 23a is withdrawn from the limiting hole 400d, the end of the limiting column 23a can be lower than the groove wall of the mounting groove 20a, or the limiting column 23a can be partially protruded from the groove wall of the mounting groove 20a, as long as it does not affect the rotation of the treatment head 10. The limiting column 23a can be arranged on the groove bottom of the mounting groove 20a, or can be arranged on the side wall of the mounting groove 20a, which can be arranged according to the actual situation.

[0169] Further, please refer to FIG. 33-34In an embodiment, the limiting column 23a is elastically mounted in the handle 20. Through the elastic mounting of the limiting column 23a, when there is no external force, the length of the limiting column 23a extending out is that it can enter the limiting hole 400d, thereby playing a limiting role on the treatment head 10; when the limiting column 23a is subjected to an external force, the limiting column 23a moves towards the inside of the handle 20, and the limiting column 23a exits the limiting hole 400d. Because the limiting column 23a is elastically mounted on the handle 20, when the treatment head 10 and the handle 20 are cooperatively rotated, the end of the treatment head 10 presses against the limiting column 23a, and when the limiting column 23a just aligns with the limiting hole 400d, the limiting column 23a rebounds and falls into the limiting hole 400d, at this time, there will be a "plop" sound, indicating that the treatment head 10 and the handle 20 are successfully installed, otherwise the cooperation of the two is not correct.

[0170] Please refer to FIG. 33-34 In an embodiment, the handle 20 is provided with a button 24, and the button 24 is connected with the limiting column 23a to drive the movement of the limiting column 23a.

[0172] Please refer to FIG. 32 and FIG. 35 The user presses the button 24 to make the cantilever 25 move downwards, at this time, the protrusion 25a has a downward moving force on the guide block 23c, because of the setting of the inclined surface 25b of the protrusion 25a, the guide block 23c is pushed to move away from the mounting groove 20a, which drives the connecting rod 23b to move backwards, so that the limiting column 23a on the connecting rod 23b moves towards the inside of the handle 20. In this way, the up-down movement is converted into the axial movement of the handle 20, which ingeniously drives the movement of the limiting column 23a.

[0173] There are various ways to realize the elastic movement of the limiting column 23a in the axial direction of the handle 20, please refer to FIG. 35In an embodiment, the connecting rod 23b realizes the elastic movement of the limiting post 23a through the elastic member 26.
